What brain structure directs sensory and motor neuron pathways passing between spinal cord and cerebral cortex?
dendrons
What are sensory neural pathways?
The sensory neural pathways set the brain's ability to interpret signals that control intellectual, emotional, psychological and physical responses to stimuli. The sensory systems ie. vision, hearing, touch, taste, smell and proprioceptor motion bring sensory signals to the brain and then interpret those signals. During development there is a critical period for sensory neural circuits. To form what is known as synapses (the connection between neurons that helps to carry these signals from neuron to neuron ), stimuli is needed. When this stimulation is not available in the critical period and deficits occur in the region of the cortex responsible, it can not be corrected at a later stage.
What is an interneuron?
An interneuron is a special nerve cell that communicates directly between the sensory and motor neurons instead of first going to the brain.
What is an internueron?
A cell that connects sensory and motor pathways for reflexes.
What is the main function of interneuron?
interneurons are located in the brain and spinal cord. They are stimulated by signals reaching them from sensory neurons. they process that information and send a response through the motor neurons.
What are sensory pathways that are located in the spinal cord or brain referred to?
Nerves
What are the two pathways by which messages are transmitted?
1 sensory organ - sensory nerves - spinal cord - brain 2 brain - motor nerves - spinal cord - muscles
What are the four Parts of the Sensory Pathway?
Sensory pathways function to provide us with information about our environment. The four parts of the sensory pathway are receptors, sensory neurons, sensory tracts, and sensory areas of the brain.
What does a sensory system include?
A sensory system includes the sensory receptors, neural pathways, and the parts of the brain which are involved in sensory perception. The senses act as the transducers from the physical world to the mind where the information gathered by the senses is interpreted.
What brain structure directs sensory and motor neuron pathways passing between spinal cord and cerebral cortex?
dendrons
What is the difference between afferent and efferent pathways?
The major difference is the direction of travel for nerve impulses. In the afferent nervous system, the impulses are traveling away from the brain - these tend to be motor impulses. In the efferent nervous system, the impulses are traveling towards the brain - these tend to be sensory impulses.
Impulses from the sense organs travel to the brain along what?
Sensory neurons

Ascending pathways in the spinal cord convey what?

What pathways form communication networks in the brain?
